Wavelength = (speed) / (frequency)
The speeds of the two possible signals are equal, just like
all other forms of electromagnetic radiation.
Wavelength of 895 MHz = (3 x 10⁸ m/s) / (8.95 x 10⁸/s) = 0.335 m
Wavelength of 2560 MHz = (3 x 10⁸ m/s) / (2.56 x 10⁹/s) = 0.117 m
Answer:
Push and pull both are forces , but the difference is in their direction at which it is applied . If the force applied in the direction of motion of the particle then we call it as push . If that force applied in the direction OPPOSITE to the motion of particle then it is termed as pull
Answer:
in squash, the balls are quite small and come in a variety of
speeds, ranging from extra- super slow to fast
Explanation:
Answer:
2 N/m
Explanation:
Given that
The length of a wire, l = 15 m
Force on the wire, F = 60 N
Surface tension on the liquid, S = ?
The formula to solve this problem is given as
F = S * 2 L, where
F = force on the liquid
S = surface tension of the liquid
L= length of the wire
On substituting the values of each, we have
60 = S * (2 * 15)
S = 60 / 30
S = 2 N/m
Thus, we can say then, that the surface tension of the liquid is 2 N/m
